3D打印高仿真教学模型在胸腰椎骨折规范化诊疗培训中的应用
Application of 3D-printed high-fidelity teaching models in standardized diagnosis and treatment training for thoracolumbar fractures
摘要
Abstract
Objective:To construct a 3D-printed high-fidelity teaching model for thoracolumbar fracture and evaluate its application efficacy in standardized clinical training for orthopedic residents.Methods:A prospective non-randomized controlled trial was conducted.80 standardized residency trainees who completed their orthopedic rotation at Tangdu Hospital from September 2025 to April 2026 were selected.They were divided into the control group(n=40,enrolled September-December 2025)and the observation group(n=40,enrolled January-April 2026)by enrollment time.The control group received conventional teaching,while the observation group received theoretical instruction,thoracolumbar fracture classification training,and pedicle screw placement simulation training using 3D-printed high-fidelity teaching models.Both groups had a 6-hour curriculum.Theoretical knowledge scores,practical skills[global rating scale(GRS),screw insertion time,screw insertion accuracy],teaching satisfaction,and general self-efficacy scale(GSES)score were compared between the two groups.Results:There were no significant differences in theoretical scores or GSES scores between the two groups before teaching(P>0.05).After teaching,the observation group showed significantly higher scores in theoretical knowledge(immediate and 4-week follow-up),practical skills teaching satisfaction,and GSES compared to the control group(P<0.05).Conclusion:The 3D-printed high-fidelity teaching model can help to improve the theoretical knowledge,pedicle screw placement skills,and self-efficacy of residents undergoing standardized training,thus can serve as a valuable supplement to conventional teaching methods.However,given the single-center,small-sample,non-randomized design,its generalizability requires further validation through larger-scale teaching practice.关键词
